Let customers speak for us
from 149 reviewsStill waiting for the power to trip. I know its a weird ask, but would like to test the system and see what it has to offer.
Still figuring out how the battery usage is managed, but as for the rest it operates seamless.
Got the app operational with a little help from my friend and gives useful information. Enjoying the Deye 12kW journey.
Still need to neaten-up the wiring though.
I thank you.
Overall, this inverter has exceeded my expectations. Highly recommended to anyone
100% delivery on time
Since we put them in the power has not tripped. So will wait and see. The service from Solar Step has been great though. Really nice people.
I am very happy with the product and the quality thereof, I am also very happy with the service received and will most definitely be doing business with the solar step again.

Thanks for your excellent service only the courier company took long for the delivery
Excellent service.
Good product
"I'm loving my GenXair Inverter AC! 😊 The energy efficiency is on point, and it's kept my space comfy all summer. The smart climate control is super handy – love being able to adjust temps remotely. It's quiet too, so no annoying background noise. Would definitely recommend for anyone looking to upgrade their cooling game!"
Very professional and I will certainly be purchasing again
Haven't used it yet but very happy with what i got and quick delivery. Thanks to the guy who informed me about the best product that will work in my situation. Got a lifePO4 100Amp battery and a charger witch is perfect for my 48lbs trolling motor. Thnx for your good and speedy service, im a very happy chap.
Thanks soo much for the great service you guys gave me with my GENX GYSER thats faulty immediately told me to sent it back and give me a new one now that i call service did not ask any questions immediately told me to fetch a new one keep up the good work will recommend to anyone

Thus far ,this inverter is one of the better ones available,I had an Ohai 4 kKw for two weeks blew IGBT's and very noisy on Rf spectrum,this Must inverter is silent not a lot of fan noise and just great quality all round,very pleased with it
